"Emotional intelligence, therefore, requires a brain that can use prediction to manufacture a large, flexible array of different emotions. If you’re in a tricky situation that has called for emotion in the past, your brain will oblige by constructing the emotion that works best. You will be more effective if your brain has many options to choose from. If your brain can only make stereotypic instances of smiley happiness and pouty sadness, then that is all you will experience and perceive in others. But if your brain is equipped to make you scowl in anger, smile in anger, widen your eyes in anger, squint in anger, shout in anger, stew silently in anger, and even bond with others over anger, then your brain can more finely tailor your emotions and behavior to the situation. In other words, you have better tools to be emotionally intelligent."
